thank you

-all key terms in section

be able to describe and identify each for 4 states of matter (solid, liquid, gas, & plasma)

1.  diagram of particle interaction

2. shape/volume for each (ex:-liquid- have a definite volume, but not a definite shape. they take shape of their container)

3. particle interaction for each (ex: solid- particles are locked in place and only vibrate in place)

 

go to link given below and complete following for EXTRA CREDIT (20 points):

 

-draw container with each layer shown in youtube video

-label with name of each substance in each layer

-label with substance's density

 

for extra 20 points, 40 total extra credit points, complete same experiment shown in video with at least 6 of the substances.  take picture and either print picture of you holding container, or email me picture with you holding container at: [email protected]
